ASTM E2329-10
(Practice)Standard Practice for Identification of Seized Drugs
Standard Practice for Identification of Seized Drugs
SIGNIFICANCE AND USE
These are minimum requirements applicable to the identification of seized drugs.
It is recognized that the correct identification of a drug or chemical depends on the use of an analytical scheme based on validated methods and the competence of the analyst. It is expected that in the absence of unforeseen error, an appropriate analytical scheme effectively results in no uncertainty in reported identifications.
This practice requires the use of multiple uncorrelated techniques. It does not discourage the use of any particular method within an analytical scheme. Unique requirements in different jurisdictions may dictate the actual practices followed by a particular laboratory.
SCOPE
1.1 This practice describes minimum criteria for the qualitative analysis (identification) of seized drugs.
1.2 Listed are a number of analytical techniques for the identification of seized drugs. These techniques are grouped on the basis of their discriminating power. Analytical schemes based on these groupings are described.
1.3 Additional information is found in Guides E1968, E1969, and E2125 and Practices E2326 and E2327.

diminishes its discriminating power.
